The raw fibres for the manufacture of upholstering material, especially the so-called vegetable horse hair, are generally placed on the market in the form of rope-like twisted Ahanks which for the purpose of the further treatment are untwisted and carded.

My invention relates toa machine which effects the untwisting and carding in one operation. y y

The frame for the untwisting and carding machine proper is a casing 1 in the upper part of which the driving motor 2 is mounted. The front part of the shaft ofthis motor is elongated (in Fig. 1 towards the right) and bears a pulley 3, a fan 4 and a rotaryhead 5. The pulley 3 and the fan 4 form a single casting the parts of'which are coherent at their hubs. The said casting is flanged at 9 to the rotary head ,5., Between the pulley 3 and the fan 4 there is a separating wall and between the fan 4 and the rotary head 5 a sieve-like wall 7 is provided.

y The rotary head 5 extends with its free front end into a circular aperture 10 of the front wall '10"L of the casing (Fig. 5). According to the preferred embodiment of the invention illustrated in the drawing the rotary head consists of an outer jacket 11 in which a sleeve 12 is detachably inserted. The

said sleeve is hollow-shaped like a blast-pipe and provided with a front flange 13 which lits into a corresponding boring in the out er jacket 11. On its rear end the sleeve 11 is provided with a stud 17 fitting into a central bore of the jacket 11 and being connected with the latter by means of a screw 18. The cavity of the sleeve grows wider towards its free end like a funnel and extends from its free end towards its inner end at first in an axial direction, then turns outwards with a slight curvature in such a way that the outlet mouth at the inner end of the cavity is in a plane forming an acute angle with the axis of the rotary head and being placed on the periphery of the sleeve in a radial` distance from its axis. Opposite to this mouth a correspondingly shaped circular aperture is provided in u.

ring 15 of the sleeve 12 is inserted into a bore of an extension of the said sleeve and detachably connected with this extension by means of screws 16 (Fig. 7). After loosening the screws the ring 15 may be turned. In this way the wear is equally distributed over the ring s'o that it may be used for a rather long time, before it must be replaced. The ring 15a is also connected with the jacket 11 by means of screws 16a.

The rotary head is located in a partition 45 of the casing. The said rear wall of the partition is formed by the grating 7 and towards one side vof the machine the partition has a cap-like extension 46 (Fig. 2) which is open on its lower side at 47 so that the material worked up may fallout downwards.`

The partition 45 is providedon its top with or carding teeth are fastened to a plate 194 which is rotatablv mounted on the cover 20- by means of a stud 19".

tory arrangement of the carrier 19 allows some yielding movement of the teeth 19 under the influence of the fibres being whirled towards the teeth through the action of the rotary head.

The supply of the hank is effected by means of two superimposed rollers 24 and 25 the lower one of which 24 is driven from the motor 2. The roller 24 and a worm wheell 27 are keyed to a shaft 26 which is mounted in the front part of the frame of the machine. The worm wheel isin mesh with a warm 28 keyed to a shaft 29 to which also a pulley 30 is fastened being connected by means of a belt 31 with the pulley 3 fixed to the motor shaft. The upper roller 25 is mounted between the limbs of a frame 32 which by means of a shaft 33 being mounted in the front wall of the box is sus ended so as to be capable of being oscillate.

The shaft 33 is provided on one of its ends with an arm 34 which is bent olf at a right angle and provided with a set screw 35 through which the lever 34 leans upon the front wall of the casing. The other end of the shaft'33 is bent to form a crank arm 36 which is connected with a pedal 38 by means of a ro'd 37. By means of this pedal the frame 32 bearing the roller 25 may be lifted (Fig. 8). F orfixing the frame in its lifted position a ratchet lever 39 is provided.

`The lower roller 24 is provided with five or another plurality of longitudinal ribs intersected by ooves so that the cross-section of the roller 1s a star with five points (Figs. 1 and 8). The ooves are cutout for the reception of the t ickenings of the hank, whilst the ribs are adapted to take the hank along. The upper roller 25 is provided with a helical rib. The interstices between the several portions of the helical rib are groove-like shaped. On the ends of the roller 25 flangesha d weights 25'* vare provided.

e space between the walls 6 and 7 (Fig. 1) is communicatingdownwards with a chamber 42 in the box-like frame of the machine.- From the rear of said box a pipe 43' illustrated through which waste fibrous material is worked up. Such waste-material is obtained in upholstering workshops in which the machine is employed. The auxiliary device allows the machine as specified to be'also used for'working up the said waste-material.

The deviceconsists of a funnel 60 which laterally enters into the space 45. In the in terior of the said funnel two superimposed rollers 56, 57 are rovided. The cross-sections of the said ro lers may conform to that of the roller-24, and the lower, roller mary be driven in the direction of the arrow as illustrated in Fig.- 13. For this purpose a wormwheel 56a being in mesh with a worm 55 is keyed to the shaft of the said roller. On the worm-shaft 54 a pulley 52 is keyed which is connected by means of a belt 51 with a pulley keyed to the shaft 26 which is driven from the motor 2 by means of the worm-gear 27, 28. The connection of the funnel 60 with the box-like frame is effected by flanges 63 which extend upwards and downwards into horizontal notches 64 of the through the rollers 56, 57 to the revolvingv willowing teeth 59 and carded by the said revolving teeth.

The working ofthe 'machine is as follows:

After liftin the upper roller 25 the hank A to be worke up is ushed through the free orifice of the rotary ead 5 into the central cavity of the same so that the hank projects. through the outlet mouth of the rotary head.

By releasing `the ratchet lever 39 the roller 25 is then lowered` to seize the hank. The

amount of lowerin of the roller may be regulated by means o a set-screwl (Fig. 3). As soon as the driving motor isv set going the spiral ofthe hank is canceled through the rotary motion of the rotary head, so that the untwisted end of the hank passes through.

the outlet mouth of the rotary head into the space 45 and is here whirled towardsthehackling orcarding teeth 19 and transformed thereby into a loose material which is thrown out through the cap 46. The said material -may be collected 1n containers which .are

placed below said ca Thereby the dust is sucked up throu h t e sieve -7 by the action of the fan 4 and rought together with short" ibr'ous material to the chamber 45 from which the air ma escape through the pipe 43. The helical s ape of the rib of the upper feeding roller 25 4has the purpose of working against the'tendency of the hank to be displaced towards one side corresponding to its spiral -when being fed into the'rotary by the effect of the screw so that with a pitch position of the cover 20.

of the screw correspondin to the feeding velocity the-.hank remains 1n th`e middle of the cavity of the rotary head.

For working up hanks of different diameters several sleeves 12 are provided the hank guides of which are of different widths. The outer shape of the several sleeves is the same so that they 'all fit into the outer jacket 11 of the rotary head. Also by adjusting the carrier 19 for the Ahackling teeth 19 an accommodation to the material to be worked up may be eected. The distance of the teeth 19 fromthe rotary head is altered by a corresponding adjustment of the angular The cavity of the rotary head may also be shaped as shown in Fig. 14 wherein thecavity has the shape of a bore ending in an enlarged central orifice at the free end of the rotary head and extending towards' its inner end in a substantially straight line forming an acute angle with the axis of the revolving head. The outlet mouth of the cavity of the rotaryhead is oppositeto the hack- Aling teeth.
